Smart meters: how to make a power play for energy management

Smart meters automatically send energy readings to your supplier, eliminating the need for manual submissions and providing real-time data on your consumption. This technology is foundational for accurate billing and offers a pathway to more informed energy management, moving beyond the traditional "use less" narrative to one of optimisation and control.

What is a smart meter and how does it work?

A smart meter is an advanced energy meter that digitally records your electricity and gas consumption, replacing older analogue meters that required manual readings. Unlike traditional meters, smart meters communicate directly with your energy supplier, sending your usage data automatically. This capability ensures that your bills are based on actual consumption rather than estimates, providing greater accuracy and transparency.

Beyond the basics: real-time data and accurate billing

The core function of a smart meter is to provide real-time energy usage data. This means you can see how much electricity and gas you are using as you use it, rather than waiting for a monthly or quarterly bill. This immediate feedback is crucial for understanding your energy habits. For instance, you can observe the impact of turning on specific appliances or adjusting your heating, allowing for more precise control over your energy use. This real-time visibility helps to end estimated energy bills, which have historically been a source of frustration for many households.

The In-Home Display (IHD) explained

Most smart meter installations include an In-Home Display (IHD), a small portable screen that shows your energy consumption in near real-time, typically in pounds and pence. The IHD acts as a visual interface for your smart meter data, allowing you to monitor your usage without needing to log into an app or check your meter directly. It provides immediate feedback on how much energy you are consuming, helping you to identify energy-intensive activities and make adjustments. Some IHDs also display historical usage data, allowing you to compare your consumption over different periods.

The benefits of smart meters for your home

Smart meters offer more than just accurate billing; they are a tool for empowering households to make smarter energy choices and prepare their homes for future energy technologies. The national smart meter rollout in the UK aims to upgrade millions of homes, fostering a more dynamic and efficient energy system.

Empowering your energy choices

With real-time data at your fingertips, smart meters enable you to make informed decisions about your energy consumption. By understanding when and how you use energy, you can identify opportunities to shift usage to off-peak times, take advantage of smart tariffs, or simply reduce waste. This level of insight transforms energy management from a passive acceptance of bills into an active "power play" where you have genuine control. For example, the average UK home uses around 2,500 kWh of electricity per year, a figure set by Ofgem's medium typical domestic consumption value (TDCV) from 1 July 20261. Your smart meter data can show you how your consumption compares and where you might adjust.

Future-proofing your home energy system

Smart meters are a foundational technology for the evolving energy landscape. They are essential for integrating future home energy technologies such as electric vehicle (EV) charging and home battery storage systems. By providing granular data, smart meters allow for optimised charging schedules and intelligent energy storage, enabling you to use energy when it is cheapest or cleanest. This capability supports a shift towards a more flexible and resilient energy system, where households can actively participate in managing their demand and even contribute to grid stability.

Addressing common smart meter questions and concerns

While smart meters offer significant advantages, it is natural to have questions about their operation, particularly concerning data privacy and the transition from older meter types.

Data privacy and security

Concerns about data privacy are understandable when new technologies are introduced. Smart meter data collection and usage in the UK are subject to strict data protection regulations, including the General Data Protection Regulation (GDPR). Energy suppliers are legally required to protect your data and can only use it for billing and energy management services, or with your explicit consent for other purposes. You have control over how your energy usage information is collected and used, and you can typically choose the frequency at which your data is shared with your supplier. Ofgem, the energy regulator, oversees these protections, ensuring consumer privacy and control over their information.

Understanding the radio Teleswitch service (RTS) switch-off

A significant development in the UK's energy landscape is the phase-out of the Radio Teleswitch Service (RTS). RTS meters are an older type of electricity meter that uses a longwave radio signal to switch between peak and off-peak rates, commonly used for tariffs like Economy 7. This service is being phased out across the industry, with the phase-out having begun on 30 June 2025.

This means that if you have an RTS meter, your energy supplier will need to replace it with a smart meter before the service is decommissioned. The replacement of these legacy meters with smart meters is part of a national upgrade programme. It is important to note that you cannot complete a switch to a new energy supplier, such as Fuse, while you still have an RTS meter. Your current supplier is responsible for replacing your RTS meter with a smart meter, typically at no cost to you. Once your meter has been upgraded, you will then be able to access the benefits of smart meter technology and switch to a supplier like Fuse for an enhanced energy management experience.

Getting your smart meter: the next steps

The process of getting a smart meter is designed to be straightforward, and leveraging its features can significantly enhance your energy management.

Eligibility and installation

Smart meter installation is typically free for eligible customers in the UK. To get a smart meter, you simply need to contact your current energy supplier. They will arrange an installation appointment at your convenience. The installation process is carried out by a qualified engineer. You do not need to do anything to prepare for the installation other than ensuring clear access to your existing meters.

Making the most of your smart meter with the Fuse app

Once your smart meter is installed, you can begin to unlock its full potential. The Fuse app, for instance, integrates directly with your smart meter data, providing you with granular insights into your energy consumption. This goes beyond just monitoring; the app enables advanced energy management, allowing you to track usage patterns, understand costs, and make proactive choices. Fuse offers free smart meter upgrades for eligible customers, making the transition to smarter energy management seamless and accessible.
